OIL IN WATER ANALYSIS
The Infra Cal 2 ATR-SP analyzer is designed to measure solvent extractable material (oil and grease) by infrared determination in water or soil using hexane, pentane, cyclohexane or Vertrel MCA for the extraction procedure. A detector with a fixed 3.4 µm (2940 cm-1) filter is used to measure oil and grease concentrations. The ATR-SP correlates with EPA Methods 1664 as well as with the ASTM D7066 Method and EPA 413.1 and 418.1.
The ATR-SP makes use of the fact that oil and grease can be extracted from water or soil through the use of an appropriate solvent and extraction procedure. The extracted hydrocarbons absorb infrared energy at a specific wavelength and the amount of energy absorbed is proportional to the concentration of hydrocarbons in the solvent. The analyzer can be calibrated to read out directly in the desired units such as, %, ppm, mg/L or mg/kg.
The touchscreen display includes the capability for multiple calibrations, a wizard guide for calibration, multilevel user database, and multiple languages with user preference selection, high/low alarm and control limits, and measurements stored in a history table for recall or export to a flash or serial port.
Key advantages
- Quickly and accurately measure TOG (total oil & grease), FOG (fats, oil and grease) and TPH (total petroleum hydrocarbons) in produced water, industrial wastewater and soil.
- Petrochemical industry standard ensuring oil content levels in produced water, drill cuttings or soil are below the regulated limit.
- Easy to operate.
